Marco Giustiniani (died 1438) was a Venetian politician who served successively as podestà (governor) of Padua (1425), Bergamo (1428) and Verona (1433).
[1] Although Marco excelled his brother Leonardo during their Latin studies, he showed little interest in learning after he began his political career.
[2] When Leonardo translated the life of Phocion from Plutarch's Parallel Lives, he dedicated it to Marco.
[3] During Marco's tenure in Padua in 1426, someone claimed to have found the bones of Livy, although this was later exposed as a fraud.
[1] Leonardo's son, Bernardo, intended to write biographies of his father and Marco, as he had of Lorenzo, but never got around to it.
